Doppler shifts precision and accuracy are the traditional aspects of spectral fidelity, but there are many others, such as: how well are the spectra characterized for noise, scattered light, detector effects, instrumental profile? What are abundance realistic uncertainties? Is precision enough or is accuracy required? Which are the limits of precise and accurate spectroscopy and which exciting science will new performances enable? Which science require spectral fidelity and how can we enable it? What is its present status and future perspective? With the installation of HARPS at the 3.6m telescope in La Silla 20 years ago, ESO community has a central role in this research. HARPS has been transformational, paving the way to the new generations of planet hunters. The aim of the conference is to discuss all the above topics, with a view to the long heritage of HARPS, the first 5 years of operations of ESPRESSO, the new results from NIR spectrographs, and future spectrographs such as ANDES at the ELTs.

Venue:
The conference will be held in the beautiful Istituto degli Innocenti, Piazza SS Annunziata, Firenze. The number of participants in presence is limited to 120 due to the conference room capacity, on a first come, first served basis. However, a hybrid format will be offered with the possibility to attend the meeting online. All speakers (both invited and contributed ones) will attend in-person.
Beginning of September is still high season in Florence. It is strongly recommend booking your accommodation as soon as possible.
